Summary

stats/<user>.yaml is team-visible, but nothing on the push path filtered skill names: a member's local-only skills, slash-command names and stray SKILL.md reads were merged verbatim and published to everyone who pulls (#1055). The only escape was usageReport: false, which also drops votes, digest stats and token contributions.

This filters at the push boundary — the privacy-relevant edge — while local usage.jsonl keeps full fidelity:

• mergeStatsWithinTeamSkills reduces aggregateUsage output to names present in the team repo's shared skills catalog (collectTeamRepoSkills, now exported) before merging, and prunes names published before the filter existed on the same rewrite — they were published by accident. This is the "prune" default I flagged in the issue comment; if maintainers prefer conservative (stop new additions, keep already-published names), dropping the prune loop is a two-line change.
• The catalog is always enumerated from the default-branch repo path, never from the write worktree: the reports branch is an orphan branch (utils/reports-branch.ts) and never carries skills/, so enumerating from writeRoot in reports-branch mode would wrongly drop all stats. This is called out in a comment at the enumeration site.
• Votes, interventions, prompts/tokens and daily stats are untouched (Stats fields (sessions/prompts/tokens) clobber each other on overwrite in reportUsageToTeam #425 partial-report semantics preserved — covered by a test).
• A team that shares no skills gets an empty skills map: every skill is local-only in such a team. Privacy-correct but a visible behavior change for teams that currently see counts — flagged for the release notes.

Type of Change

• Bug fix (non-breaking change that fixes an issue)
• New feature
• Breaking change
• Documentation only
• Refactor / internal cleanup

Test Plan

• npx tsc --noEmit passes
• npm run lint passes (oxlint, 0 warnings / 0 errors)
• npx vitest run — new team-push-privacy.test.ts (6 tests) plus the push/stats/usage family (165 tests) all pass; the only failure anywhere remains the pre-existing environmental dsh-hooks case (DSH installed locally, fails identically on clean main)
• Red/green verified: all 6 new tests fail against pre-fix src/team-push.ts/src/agent-skills.ts and pass with the fix

Fixes #1055

Notes for Reviewers

• The one design call from the issue thread: prune vs. conservative for already-published names. This PR implements prune (full remediation); say the word and I'll flip it.
• Name matching is exact on bare names — the same shape event.skill records and the catalog keys use. An exotic namespaced spelling would be filtered rather than leak (privacy-safe direction of the false negative).

Real-CLI verification record (P1)

After npm run build, against a bare-origin fixture whose team repo shares skills/review, with the user scope's usage seeded as 3× legacy (older) + 2× review (newest) in ~/.teamai/user-usage.jsonl:

$ node dist/cli.js pull
✔ [user] Team repo: already up to date
✔ [user] Already synced at 16ce3ff, skipping

$ git -C origin.git show teamai-reports:stats/verifier.yaml
username: verifier
updatedAt: 2026-10-16T06:57:12.173Z
skills:
  review:
    count: 2
    lastUsed: 2026-10-16T06:57:11.000Z

review publishes with its count; legacy — a name outside the team catalog — is kept out of the team-visible stats while the local usage file keeps full fidelity. (Workflow-run stats from the earlier fixture history were replaced by this fresh report.)

Branch note (CI failures root-caused)

The earlier E2E failures on this branch were not caused by these commits: the PR's merge ref was built against a main state whose squash of #1126 had dropped the two e2e expectation fixes (d25b7ae predates them being restored on main by #1161), so the merge ref combined the records engine with the pre-records test expectations. The branch is now recreated on current main (same three commits, 56bb9cc..c657ae7); all four affected e2e files pass locally after a fresh build (65/65), unit suites 172/172, tsc and lint clean.

Filing team here — we opened #1055, and we have a direct answer to the design call in your Notes for Reviewers.

Prune: yes, please. The names in already-pushed stats/<user>.yaml were published by accident; the merge rewrites the file on every push
anyway, so leaving them keeps exactly the disclosure the issue is about. If maintainers prefer conservative (stop new additions only), a
release-note line becomes mandatory — readers of the leaderboard otherwise can't tell leaked names from intended ones.

One reverse case worth covering: filtering strictly by the repo catalog also drops the built-in teamai skill (deployed by the CLI,
served via teamai skill get, never present in skills/). If the digest is meant to show adoption of the built-in skill, the catalog
probably needs to include built-in/served names too — otherwise that signal silently disappears. Not a blocker for this PR, just worth a
line.

Context that may help the review: our team runs Codex only, where no payload records a real skill use (no Skill tool, no Cursor-style
SKILL.md read). Everything we saw in our stats was the slash-command path misreading prompts that start with a path — /disk0/users/... →
disk0, /tools/home/... → tools. Your filter removes that noise as well, which we appreciate. Local usage.jsonl staying full-fidelity
while the filter sits at the push boundary is exactly the shape we hoped for.

[hsuchifeng]

Thanks for the fix. Please don't prune names already in stats/<user>.yaml. They remain in the git history either way, and rewriting that history is costly. Filtering new usage to the team's shared skills is enough.

@hsuchifeng Done — 9f0b872 flips to conservative: previously-published names are kept as-is (the function now only filters new usage; the doc comment records the maintainer call), and the prune test inverted to pin the new contract.

@shusun-lu Your built-in point is covered too: teamSharedSkillNames now unions BUILTIN_SKILL_NAMES, so the CLI-deployed teamai skill (never present in skills/) stays publishable — covered by two new tests (catalog carries built-ins with no skills dir; built-in published from new usage). The slash-command noise you traced (/disk0/... → disk0) is confirmed filtered in the run below.

Real-CLI verification (the P1 record, built dist/index.js end-to-end against real git remotes):

Setup: team repo with skills/shared-skill/, member project (project scope), usage.jsonl with 5 events — shared-skill ×2, my-private-skill, teamai, disk0 (slash-command noise).

• teamai push --all → resources branch pushed
• teamai pull → teamai-reports orphan branch written; stats/alice.yaml on the remote contains exactly:

skills:
  shared-skill: { count: 2, ... }
  teamai:       { count: 1, ... }

my-private-skill and disk0 are absent from the published file, and the local usage.jsonl keeps all 5 events (full fidelity, filter sits only at the push boundary). Unit family 37/37 green, typecheck + oxlint clean.

CI is currently failing across all Node/OS jobs: 4 unit tests in git-kind-reports.test.ts and team-push-interventions.test.ts, plus 15 E2E cases in report-timeout.test.ts. The expected skills are being filtered out and are missing from the generated stats. Please fix the implementation or update the fixtures to include the intended shared skills, then rerun CI.

[kittimzhe]

Both points are already handled on the branch:

• No pruning of published names — commit 9f0b872 removed the prune loop before your comment landed: only new usage events are filtered to the team's shared skills (plus the built-in teamai skill), and whatever is already in stats/<user>.yaml stays untouched.
• The CI failures are fixture gaps, fixed in 74ad8d1 — those 4 unit + 15 E2E cases record usage for skills (review, skill-a, skill-c) whose seeded team repos ship no skills/ catalog, so the new filter correctly drops them. The tests' intent (scope isolation, reporting mechanics, report completion) doesn't depend on the privacy filter, so the fixtures now seed the skills they expect to be published — team-push-interventions gets skills/review, git-kind-reports seeds skill-a/skill-c per team, and the E2E report-timeout fixture seeds skills/review before the initial commit. All three files pass locally (28 + 19 E2E), the full unit suite is green except the known dsh-hooks environmental case documented in the PR body, and typecheck/lint are clean.

The 74ad8d1 run hasn't started yet — it looks like the fork CI trigger still needs authorization. Could you approve the workflow run when you get a chance? Happy to adjust further if anything else comes up.

[hsuchifeng]

CI on the current head 9f0b872 is still red, and it is this change, not an infra flake.

reportUsageToTeam now drops any new skill that is not in the team repo skills/ catalog or the built-in teamai name. The suites that failed record usage for names those fixtures never share:

• git-kind-reports.test.ts — expected [] to deeply equal [ 'skill-a' ] (reportedSkills at the scope-isolation case)
• team-push-interventions.test.ts — stats.skills.review is missing, so .count throws (3 cases: push false, push rejection, folded side-file id)
• report-timeout.test.ts — same .count throw, 15 cases (skills.review / skills.legacy)

That is all six Lint & Test jobs plus E2E (fork-safe). Run 38337680378.

74ad8d1 does seed review / skill-a / skill-c into those fixtures, but it is not on fix/stats-skill-privacy. Its parent is 47d62532 (docs(hooks): state the version-floor tradeoff), and the PR branch is still 9f0b872. Please cherry-pick that fixture commit onto this branch and push it, so CI actually runs the fix.

[kittimzhe]

Apologies — 74ad8d1 had landed on the wrong local branch (fix/zcode-hooks-keeplist) instead of fix/stats-skill-privacy, which is why the PR head stayed at 9f0b872. Cherry-picked onto this branch as e9248b8 and pushed; the PR head is now e9248b8.

Verified the three suites you named, locally:

• git-kind-reports.test.ts — 19/19 (the skill-a scope-isolation case passes)
• team-push-interventions.test.ts — 9/9 (stats.skills.review.count no longer throws)
• e2e/report-timeout.test.ts (vitest.e2e.config.ts) — 19/19

npm run typecheck and npx oxlint clean. Ready for the CI rerun — it will still need the fork-safe workflow authorization on this push.

Please resolve the conflict.

[kittimzhe]

Rebased onto main — the conflict was the writeReportFiles signature (main added the votesStaged parameter in the votes V2 merge); both changes are kept, with the shared-skill catalog enumeration preserved inside the merged signature. All 457 team-push/report-related tests pass on the rebased branch.

The CI failure on 5f865fe is a timing flake, not a regression: report-timeout.test.ts > a reporting scope over the cap keeps every event written after the report read it fails after an 18s timeout on the fork runner (the TypeError: undefined.count is the post-timeout cascade). Locally on the same head it passes 19/19 — three consecutive runs — and the full report-related e2e set (report-scope-reuse, reports-writer-sync-561, dashboard-kb-report-votes-readonly) is green too. I can't rerun the fork job from here (needs admin rights); happy to rebase again to trigger a fresh run if that's easier.

[kittimzhe]

Correction on the earlier CI read: the report-timeout.test.ts failure was not a fork-runner flake — it was deterministic, and my earlier "local 3× green" was an artifact of a stale dist/ built from a different branch (branch switch without rebuild), so the filter never actually ran locally.

Root cause: the over-cap slow-receiver test asserted the pre-#1056 behavior — a skill name outside the team's shared catalog (legacy) reaching the published stats/alice.yaml. With the privacy filter that name is kept out by design; the published stats keep only shared names. The test's actual subject (events appended after the report read survive in usage.jsonl) is untouched.

Fixed in 93a1c6a: the fixture now expects legacy to stay out of the published stats and review to carry the capped count — the same shape the rejected-then-retry test above it already asserts. Verified against a rebuilt dist: isolated single-test run (the CI-equivalent shape) green, full file 19/19, team-push-privacy.test.ts 7/7, tsc and lint clean.

Two updates: (1) real-CLI verification record added to the description (P1) — a real pull publishes review: count: 2 and keeps the non-catalog legacy name out of the team-visible stats. (2) The branch is recreated on current main: the earlier E2E failures came from the PR's merge ref predating #1161's restoration of the two e2e expectation fixes that the #1126 squash had dropped, so CI saw the records engine with pre-records test expectations — not from these commits. All four e2e files 65/65 locally after a fresh build.
